Hey, so I'm trying to install SMB in Ubuntu 12.04.  It doesn't seem to be showing up in the Ubuntu Software Center.  When I search for it I get nothing, and all the links to it from various places (such as the Humble Bundle website where I bought it) bring up an error in the Software Center: "Not Found.  There isn’t a software package called “supermeatboy” in your current software sources."  All the other games from the bundle show up fine.

This seems bad, although I might be doing something wrong.
